TPS54526RSAR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54526RSAR is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a high-quality input capacitor. Additionally, the PCB layout should be designed to minimize noise and parasitic inductance.
  • The TPS54526RSAR can deliver up to 2A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The output voltage of the TPS54526RSAR can be adjusted by using a resistor divider network between the output and the feedback pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The enable pin on the TPS54526RSAR is used to turn the device on or off. When the enable pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
